函数名称：tracing_map_alloc_elts

函数原型：static int tracing_map_alloc_elts(struct tracing_map *map)

返回类型：int

参数：

类型参数名称
struct tracing_map *map
484  elts等于tracing_map_array_alloc(max_elts, *的长度)
486  如果非elts则返回:负ENOMEM
489  以i小于max_elts循环
490  *TRACING_MAP_ELT(elts, i)等于tracing_map_elt_alloc(map)
491  如果是错误则
492  * (TRACING_MAP_ELT(elts, i)) = NULL
493  tracing_map_free_elts(map)
495  返回:负ENOMEM
